A collection of funny birthday messages to send to friends: jokes and example phrases that will make them laugh out loud

Apparently, “hapiba” is already outdated slang. I was casually using it with my junior! Oh my friend, you can understand how embarrassing this is…NEW!

Every generation has its own trendy slang, right? The sender of this message used “hapiba,” a shortened form of “happy birthday,” without realizing it’s now considered outdated and that younger people don’t understand it—and ended up feeling embarrassed.

Words we used when we were young can slip out unexpectedly… I get it.

But among people of the same generation, this experience would spark tons of empathy! If you bring it up around someone’s birthday, you might even get a reply like, “Actually, I did that too…” and swap stories of slip-ups.

It could make your sense of camaraderie even stronger.

Age is just a number! Let’s keep living powerfully no matter our age!NEW!

Birthdays are a joy, but when you think about how old you’ve gotten, it’s surprising how quickly time flies, isn’t it? There are probably many people who don’t even want to think about their age.

Here’s a message I recommend for times like that! “Age is just a number”—it’s fun how it takes a positive stance on aging by boldly calling it nothing more than a number.

I also think it’s wonderful because it conveys the determination to do what you want, no matter how old you are.

Use this when you want to make someone laugh while giving them a little encouragement.

I feel 〇 years old at heart. But from today, my body is 〇 years old. While feeling the gap between my mind and body, let’s enjoy another year together!NEW!

This is a message that turns having a lower mental age than your actual age into a joke.

For example: “I feel 18… but starting today my body is 35.” I think it’s wonderful to keep your heart young forever, but on paper it’s undeniably funny.

If the gap isn’t big, it doesn’t really read as a gap, so try sending a message that pushes your mental age as low as you can within reason.

If you deliberately go with something like 5 years old, it’s clearly a joke and unlikely to make the other person feel uncomfortable!

Happy ◯◯ Birthday Festival! Thank you for being born!NEW!

“Birthday” literally means the day a person was born.

“Seitansai,” on the other hand, carries a stronger nuance of celebrating the very fact of someone’s birth.

It’s often used among fans to celebrate the birth of a favorite character or idol.

Let’s try using this term “seitansai” in a birthday message to a friend! Using this word will likely make your friend feel how much you cherish them and make them happy.

Your friend’s once-a-year birthday is the perfect time for a slightly over-the-top yet heartwarming message—why not send such celebratory words?

Happy Birthdayhamnida!NEW!

Let’s put a little twist on the classic birthday message “Happy Birthday”! In this idea, you intentionally write “congratulations” in katakana and add “-hamnida” at the end to give it a Korean-style flair.

By the way, “hamnida” is a word that corresponds to polite endings like “desu/masu” in Japanese.

It would likely delight people who love Korea or are fans of K-pop groups.

They might think it’s just a normal “Omedetou,” only to find an unexpected ending that makes them chuckle—what a fun message!

I won’t ask how old you are. That would only make me realize I’ve gotten older, too. People seem to call this escapism.

It’s wonderful to express your everyday appreciation on a friend’s birthday.

Some people might even pour their passionate feelings into a long message.

But when it comes time to actually send it, it can feel a bit embarrassing, right? That’s where I recommend using the joke, “I won’t ask how old you are.” If you put this in the latter half of your message, they’ll likely finish reading with a smile.

You could also add a self-deprecating gag after “I won’t ask” to make it even funnier.

A most happy birthday. I shall offer my congratulations next time.

One slightly intellectual joke I’d like to introduce is: “O-tanjōbi ito medetashi.

Kondo iwaitatematsuramu.” This is essentially a birthday greeting phrased like The Pillow Book.

By the way, “ito” means “very,” and “matsuramu” means “to do/perform.” In other words, it conveys: “A very auspicious birthday—let’s celebrate next time.” You could also mix in other classical-style words and make your own variations.

Even if it ends up sounding a bit arcane, the kanji and context should let the meaning come across well enough.

Well, isn’t this something to celebrate. You, who used to have such an amazing figure, have even gained an air of gravitas with that well-stocked belly. At long last, you’ve turned ◯ years old. I’m happy for you, my friend.

Have you ever received a baffling message from a friend on your birthday? It might actually have been an acrostic.

An acrostic is a kind of code where you read the first letters of each line of a horizontally written passage vertically to find a hidden message.

Think of it like a “congrats” version of an alphabet poem; that might be easier to picture.

When you try it yourself, aim to write sentences that won’t make it obvious it’s an acrostic.

Once you reveal it afterward, it’s sure to be a hit.

By the way, you don’t have to limit yourself to the first letters—you can use other positions, too.

I thought I’d grow in many ways as I got older, but the only things that actually grew were the number of wrinkles and my weight.

There are some jokes you can only make because you’re really close to someone, right? With that in mind, here’s one I’d like to introduce: “The only things that have grown are your wrinkles and your weight.” In short, it’s a jab about how someone’s appearance has changed.

But if it’s a close friend, they’ll probably shoot back with something like, “Speak for yourself.” That said, some people really are sensitive about it, so be considerate.

In that case, you can switch it up to “The only thing that’s grown is ___,” and tease them about something other than their looks.
